Precision casting kuj hu uapeev casting. Qhov txheej txheem casting no txo qis los yog tsis txiav thaum lub sij hawm casting txheej txheem. Nws yog txoj kev casting nrog ntau yam kev siv, siab qhov tseeb ntawm qhov casting, thiab zoo heev nto zoo. Nws tsis yog nyob rau hauv ultra-siab kub tej yam kev mob, thiab yog ntau haum rau casting Cheebtsam nyob rau hauv high-precision industries xws li aerospace thiab lub teb chaws tiv thaiv. Nws yog thawj zaug siv stainless hlau precision casting txoj kev los cam khwb cia cov turbine hniav nyob rau hauv nws ua aero-engine thaum lub sij hawm ntawd. Cov khoom tiav tau raug qhuas los ntawm txhua yam, thiab txoj kev no tau nthuav dav. Stainless hlau precision casting yog ib qho cuab yeej siv hauv kev lag luam foundry, tab sis nws txawv ntawm cov tsoos foundry kev lag luam vim tus nqi ntxiv ntawmprecision casting khoomyog siab dua.
Silica Sol Plhaub txheej txheem
silica sol plhaub ua txheej txheem feem ntau yog siv nyob rau hauv ntau sophisticated internal combustion cav qhov chaw casting kev lag luam. Cov txheej txheem siv no muaj kev ruaj ntseg zoo dua, tsis tas yuav muaj cov txheej txheem tshuaj tawv tawv, tiv taus qhov kub thiab txias, thiab muaj kev tiv thaiv zoo dua rau deformation. Txawm li cas los xij, cov thev naus laus zis no kuj muaj qhov tsis txaus ntseeg, uas yog, qhov sov sov ntawm cov pwm siv quav ciab kuj tsis zoo, uas tuaj yeem txhim kho los ntawm kev ntxiv surfactants, tab sis nws yuav ua rau kom cov peev nyiaj nce mus rau qee yam.
Dej iav Plhaub txheej txheem
Txoj kev no yog invented heev thaum ntxov. Peb lub teb chaws kuj tau qhia txog cov cuab yeej no los ntawm Soviet Union nyob rau xyoo 1950 thiab 1960s. Txoj kev no muaj tus nqi qis, kev ua haujlwm yooj yim, thiab cov khoom siv raw khoom tsawg. Cov yam ntxwv tseem ceeb ntawm cov txheej txheem siv paraffin-stearic acid qis-kub pwm cov khoom, thiab cov binder hauv lub plhaub ua cov txheej txheem siv dej iav, uas yog dav siv hauv stainless hlau precision casting. Txawm li cas los xij, qhov teeb meem loj tshaj plaws ntawm txoj kev no piv rau silica sol plhaub ua txheej txheem yog qhov zoo ntawm qhov tau txais castings yog qhov nruab nrab thiab qhov tseeb qhov tseeb yog tsawg. Txij li thaum pib ntawm cov cuab yeej siv no, kev txhim kho loj heev tau ua, feem ntau hauv cov hauv qab no:
1. Txhim kho lub plhaub txheej.
Qhov kev txhim kho tseem ceeb yog ntxiv qee qhov ntawm cov av nplaum refractory rau sab nraub qaum ntawm lub plhaub, uas txhim kho lub zog ntawm lub plhaub, thiab paub txog tib lub plhaub roasting thiab tua.
2. Optimization ntawm hardener.
Cov tsoos hardener feem ntau siv ammonium chloride, tab sis cov khoom no yuav tso tawm ntau cov ammonia thiab nitrogen oxide roj thaum lub sij hawm casting txheej txheem, uas yuav ua rau cov huab cua phem. Yog li ntawd, aluminium chloride tov yog siv los hloov, thiab txhuas chloride siv lead ua yog siv ntxiv. Cov nyhuv ntawm tus neeg sawv cev zoo ib yam li cov ammonium chloride, tab sis nyob rau hauv xyoo tas los no, kev siv magnesium chloride hardener muaj qhov txiaj ntsig zoo ntawm kev ua kom nrawm thiab qhov seem, yog li tam sim no nws xav tau ntau dua los siv magnesium chloride ua hardener. .
3. Composite plhaub.
Vim tias qhov zoo ntawm lub plhaub ntawm cov dej iav txheej muaj qee qhov tsis xws luag, ntau qhov qub yog cam khwb cia hauv daim ntawv ntawm ntau txheej pwm sib xyaw casting, uas txuag nqi ntawm ib sab tes thiab txhim kho qhov zoo ntawm qhov casting ntawm lwm tus. tes.
4. Kev tsim kho tshiab.
Tam sim no, cov txheej txheem tshiab uas paub tab yuav tsum yog tus kheej-priming casting txheej txheem, ua npuas ncauj yas pwm, molten pwm plhaub casting thiab lwm yam txheej txheem. Cov txheej txheem no muaj qhov ua tau zoo hauv qee qhov, tab sis kev txhim kho yav tom ntej tseem yuav nyiam cov neeg ua haujlwm tshawb fawb thiab thev naus laus zis.
Multi-technology Hla Siv nrog Rapid Prototyping Technology
Kev tsim thiab pwm tsim nyob rau hauv tus txheej txheem ntawm kev ua stainless hlau precision casting ciab pwm yog ntau nyuaj thiab siv sij hawm, tab sis ceev prototyping tshuab yuav ua tau rau qhov no shortcoming. Kev siv thev naus laus zis sai ib leeg tsis tuaj yeem siv tau vim tias cov khoom siv txwv tsis pub, ntau xyoo tsis ntev los no Kev siv cov cuab yeej polymer kom tau txais cov duab puag ncig ntawm cov casting, thiab tom qab ntawd tsim cov pwm pwm, uas yog siv hauv stainless hlau precision casting. Piv txwv li, lub teeb curing peb-dimensional qauv tshuab (SLA) thiab xaiv laser sintering tshuab (SLS). Ob lub thev naus laus zis tam sim no yog cov thev naus laus zis uas paub tab siv ua ke nrog peev casting. SLA thev naus laus zis tuaj yeem muab qhov tseeb dua qhov tseeb, tshwj xeeb tshaj yog rau qhov chaw. Qhov tseeb ntawm sab nrauv, SLS, rau qee qhov, cov khoom siv raw yog me ntsis pheej yig dua, tab sis qhov tseeb kuj muaj qee qhov sib txawv piv nrog SLA thev naus laus zis, uas tsim nyog rau qee qhov kev ua haujlwm casting nrog cov nqi yuav tsum tau ua. Txawm li cas los xij, nws tseem yuav tsum tau ua tib zoo saib xyuas qhov tseem ceeb ntawm kev sib xyaw ua ke ntawm kev siv thev naus laus zis sai thiab stainless hlau precision casting thev naus laus zis thaum siv, xws li kev txiav txim siab txog kev tswj hwm tus nqi thiab qhov raug casting qhov tseeb ntawm qhov chaw, thiab xaiv qhov tsim nyog sib npaug taw tes yog ceev prototyping technology. thiab peev casting technology. Qhov teeb meem tseem ceeb ntawm kev koom ua ke organic.
Multi-technology Hla Siv nrog Computer Technology
Txoj kev npaj tsim thiab optimization ua hauj lwm nyob rau hauv stainless hlau precision casting txheej txheem yog ib tug kuj siv zog-siv thiab lub sij hawm-siv ua hauj lwm. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho txuas ntxiv ntawm kev siv tshuab computer, ntau qhov kev lag luam uas xav tau ntau qhov kev suav thiab kev suav lej tau qhia txog kev ua haujlwm hauv computer, thiab sib xws ntau yam kev suav software tau tsim, xws li ProCAST, AutoCAD, AFSolid, Anycasting thiab lwm yam software. . Cov softwares no tuaj yeem suav lossis simulate tus tsim thiab casting txheej txheem ntawm stainless hlau precision casting. Cov txheej txheem optimization tam sim no tuaj yeem ua kom zoo los ntawm kev suav cov ntaub ntawv. Txoj kev loj hlob ntawm casting tau ua lub luag haujlwm zoo hauv kev txhawb nqa. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev siv tam sim no, peb kuj pom tias peb yuav tsum tau them sai sai rau cov qauv siv ntawm lub computer software thiab cov thermophysical tsis ntawm cov khoom nws tus kheej. Ib qho kev daws teeb meem zoo rau cov teeb meem no tuaj yeem txo lub sijhawm txhim kho ntawm stainless hlau precision casting.
